15.82 Ct. Topaz from Ceylon (Sri Lanka)

This 15.82 carat transparent oval blue topaz from Ceylon Sri Lanka is a rare combination of size, brilliance, and clarity, qualities that are immediately evident when you see it in person. Measuring 17.90 by 12.88 by 8.44 mm, the stone has been cut into an elegant oval with a mixed brilliant facet arrangement that maximizes internal sparkle while preserving weight and table presence. At eye level the gem reads as eye clean, free of visible inclusions that would distract from its icy blue charm, and the polish is excellent, creating crisp facet junctions and lively light return. The color sits at a medium light intensity, offering a fresh, wearable blue that reads as classic topaz rather than the darker tones of other marketed varieties. This stone has undergone irradiation enhancement, a standard and stable treatment in the topaz market that intensifies the blue without compromising clarity or durability. When you compare this piece to the typical commercial blue topazes you will find, the scale and overall finish set it apart, making it a superior option for a centerpiece ring, pendant, or heirloom piece.

In the marketplace many blue topazes are smaller, less clean to the eye, or heavily enhanced in ways that reduce their natural appeal. Swiss blue topaz and London blue topaz are familiar names, and those options can be attractive depending on taste, but they often come in mass produced sizes and cuts that prioritize color over proportion and clarity. By contrast this 15.82 carat oval from The Natural Gemstone Company offers a balanced approach, with a mixed brilliant cut that brings out scintillation and flash, and an eye clean clarity that delivers a clear, open window into the stone. The dimensions and carat weight give it presence without forcing you into an overly dark tone. Compared to aquamarine of similar hue, this topaz offers a brighter, crisper blue at a more accessible price point for the carat weight, and compared to many lab grown or simulated alternatives it provides the natural crystal structure and provenance that discerning collectors value. The excellent polish elevates the overall appearance so that light dances across the surface rather than appearing waxy or diffuse, which is a common shortcoming in lower grade stones.

For the conscious collector ethical sourcing matters as much as the gem itself, and The Natural Gemstone Company places provenance and responsible practices at the center of our offerings. This topaz originates from Ceylon Sri Lanka, a historic gem region known for artisanal mining and long established lapidary traditions. We work directly with trusted partners in the region and maintain transparent relationships that enable traceability from mine to buyer. Our sourcing priorities include fair compensation for miners, minimized environmental impact through supportive local initiatives, and documentation around material handling. When enhancement is present, as with the irradiation applied to this topaz, we disclose it openly and explain the reasons and stability of the treatment. For customers building a conscious collection this level of transparency matters, because it means you can wear and gift this gem with confidence that its beauty was obtained through accountable channels. Pairing this blue topaz with recycled precious metals and conflict free settings amplifies its ethical profile, and our team can advise on creation of bespoke mounts that reflect both personal style and responsible sourcing.

In practical terms this stone is a versatile, exceptional choice for someone focused on quality, value, and ethical considerations. Its substantial carat weight and clean appearance provide immediate visual impact, while the medium light blue ensures broad wearability and flattering contrast against many metal colors. As an investment in your jewelry collection it offers a strong carat for carat value compared with many smaller or lower clarity stones on the market, and its provenance and disclosed treatment support a purchase you can feel good about. The Natural Gemstone Company stands behind each piece with knowledge and service, and we are happy to discuss mounting options, certification details, and suggested care practices to preserve the stone for generations. If you are comparing options for a statement ring, a refined pendant, or a collector s cabinet, this Ceylon blue topaz delivers unmatched balance among size, sparkle, and ethical sourcing, making it a considerate and beautiful addition to any conscious jewelry collection.
